<P CLASS=para>
An <tt CLASS=literal>EOFException</tt> is thrown in 
response to an attempt to read past the end of a file. 

<P CLASS=para>
Many file-handling routines indicate the end of a file with 
a special return code. For example, many <tt CLASS=literal>read()</tt> 
methods return <tt CLASS=literal>-1</tt> to indicate 
that the end of file has been reached. However, in some cases, the program 
clearly expects a certain format of data in a file. If it's not all 
there, throwing an exception is an appropriate way to flag the unusual 
condition of the file. So, for example, a <tt CLASS=literal>DataInputStream</tt> 
throws an <tt CLASS=literal>EOFException</tt> if it 
comes to the end of file in the middle of <tt CLASS=literal>readFloat()</tt>. 
In the <tt CLASS=literal>java.io</tt> package, <tt CLASS=literal>EOFException</tt> 
is used in the classes that implement the <tt CLASS=literal>DataInput</tt> 
and <tt CLASS=literal>ObjectInput</tt> interfaces, 
namely <tt CLASS=literal>DataInputStream</tt>, <tt CLASS=literal>ObjectInputStream</tt>, 
and <tt CLASS=literal>RandomAccessFile</tt>.
